Abstract (en)
[origin: EP0798315A1] A process for the production of homogeneous mixtures (I)containing (a) metallocene(s), (b) co-catalyst(s) and (c) formulation media, in which the preparation of the catalyst system (a + b) comprises: (A) direct preparation by known methods in the hydrocarbon used (HC), or (B) suspending, dispersing or dissolving the isolated metallocene-based catalyst components in HC, or (C) adding a solution of the components in low-boiling solvent (made by known methods) to HC and then removing the low-boiling solvent, optionally with the use of (D) conventional inorganic or organic support materials, auxiliary substances and/or additives etc. Also claimed is a formulation obtained by this process.
